Product Details
This is a complete upper receiver that drops right onto any standard AR-15 lower, so you're not buying a whole new rifle to get a shorter, handier setup. It's got a 12.5-inch barrel and comes ready to shoot with all the pieces you need, including those 100 rounds of ammunition. The shorter length makes it easier to handle in tight spaces without sacrificing accuracy, and the picatinny rail gives you room to add optics or accessories down the road.
